Determining and Analyzing the Quality of GNSS RTK Positioning

The constant development of technology brought many changes into the geodetic profession. One of those changes is the usage of GNSS RTK measurement systems. The International Organization for Standardization (ISO) defines procedures to determine the precision of GNSS RTK measurement systems. This paper gives the overview of the standard ISO 17123-8:2015 which specifies and defines field procedures to be adopted when determining and evaluating the precision of GNSS RTK field measurement systems and their ancillary equipment. The testing of the precision of GNSS RTK measuring systems Topcon HiPer SR has been performed on March 8 and 9, 2018 in the test field at Klaićeva Street in Zagreb, near the Faculty of Geodesy. Coordinates and normal orthometric height present measuring data and based on them empirical standard deviations have been calculated and statistical tests performed. Based on the results obtained in testing, it’s concluded that the used GNSS RTK measuring system Topcon HiPer SR meets the measuring uncertainty declared by the manufacturer of the instrument.
